The film will be released by a partnership of Lions Gate Films, IFC Films and the Fellowship Adventure Group, which was formed by Harvey and Bob Weinstein specifically to market Moore's film.
Moore's film, which recently won the top prize at the Cannes Film Festival, criticizes President Bush's response to the Sept. 11, 2001, terrorist attacks and connects the Bush family with Osama bin Laden's.
The Weinsteins, who run Miramax Films, bought the rights to the movie from The Walt Disney Co., which owns Miramax and refused to distribute "Fahrenheit 9/11."
The Weinstein brothers will personally finance and control distribution and marketing, they said Tuesday.
"I am grateful to them now that everyone who wants to see it will now have the chance to do so," Moore said in a statement.
"On behalf of my stellar cast - GW, Dick, Rummy, Condi and Wolfie - we thank this incredible coalition of the willing for bringing 'Fahrenheit 9/11' to the people."
Disney chief executive Michael Eisner said the company "did not want a film in the middle of the political process" because he believed that theme park and entertainment consumers "do not look for us to take sides."
In a settlement reached last week, the Weinsteins repaid their parent company for all costs of the film to date, estimated at around $6 million. Any profits from the film's distribution that go to Miramax or Disney will be donated to charity.
